HAY-COOKER.

eeaooa.

To all whom it may concern:

Be it known that we, JAMES GoYNoN and LoUIs GoYN ON, citizens of theUnited States, residing at Bay City, in the county of Bay and State ofMichigan, have invented certain new and useful Improvements in Hay-Cockers; and we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

Our invention relates to hay cookers.

One object is to provide a device of this nature wherein it isunnecessary to reverse the hay receiving receptacle end for end indischarging the contents thereof, or to stop the machine whiledischarging the contents.

Another object is the provision of means for quickly dumping ordischarging the contents of the hay receiving receptacle While themachine is in motion to prevent the hay collected frombeing strewn in awindrow.

A further object is the provision of improved means for gathering orraking the hay and leading it to the receiving receptacle.

To these and other ends our invention consists of certain novel featuresand combinations such as will be more fully described hereinafter andparticularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of our invention,Fig. 2, a top plan view, Fig. 3, a rear view partly in section, Fig. l,a detail view showing the catch for retaining the hopper closed, Fig. 5is a detail of the means for raising and lowering the rakes, Fig. 6 is adetail view of the means for pivotally supporting the hopper. Fig. 7 isa top plan view, Fig. 8 is a front view, and Fig. 9 is a detail view ofthe rake.

A indicates the braced frame of our machine, the rear portion of theframe being elevated as at 1 to form a bridge whereby to support thehopper a suitable distance above the ground. This frame is supported bythe front wheels 2, 2 rotatably mounted on the stationary front axle 3,and. by the rear wheels 4: held in the forks 5, 5 which are swiveled tothe rear portion of the frame as at 6. A suitably braced U-shaped member7 is hinged as at 8 to the forward end of the frame. Thills 9 areadjustably secured to the U-shaped member to permit one horse or a teamto be hitched up.

In order to collect or gather the hay, we provide a pair of rakescomprising the converging bars 10, 10 ournaled to the underface of theframe as shown at 11 in Fig. 5, such bars having secured thereto therake teeth 12. The adjacent rear ends of the bars are first curveddownwardly as at 13 and then horizontally inwardly toward'each other asat 14t, whereby the sections 14.- are brought near the ground. As themachine traverses the field the hay will be gathered by the rakes andshunted or directed toward the center of the machine where the rakes arereduced in height. Directly behind the low rear sections of the rake islocated the lower end of an endless conveyer 15. Such conveyer may be ofany suitable style, but we prefer to use a belt conveyer equipped withsuccessive rows of teeth 16. This conveyer leads from a point directlybehind the adjacent low rear ends of the rakes to a point on the bridge1 above the open end of the hopper. As one means for raising andlowering the rakes, we provide the lever 18 secured to a shaft 21journaled in and extending across the frame, such shaft having securedthereto two arms 22, connected by links 19 to arms 20 rigidly secured toand projective from the respective rake bars. This construction is shownin detail in Fig. 5.

In order to transfer the hay from the ground to the conveyer, we lowerthe adjacent rear ends of the rakes as heretofore de scribed and impartan easy curve to the rake teeth 12 carried by the sections 1 1 to permitthe bunched hay, straw or what not to ride up the rake teeth and fall onto the conveyer. To assist this process, however, we provide kickers,consisting of a series of forks 24: the stems of which are mounted onthe cranks 25 projecting radially at different angles to each other onthe crank shaft 26 journaled to and extending across the frame. Theupper ends of the stems may be pivotally connected to the thill frame 7by the links 27, whereby when the thill frame and thills are dropped,the kickers are raised up out of the way. The stems are also providedwith the usual springs 28. As a means for rotating the shaft 26 weprovide the ring gear 29 carried preferably by one of the front wheels2. A spur gear (not shown) meshes with the teeth of the gear 29, aclutch mechanism 30 controlled by a shifting lever 31 pivoted, it maybe, on the front axle being interposed between the spur wheel and theshaft 26, whereby to cause the shaft to rotate or permit it to remainidle.

The belt conveyor is supported on rolls 32, the upper one of which ismounted on a shaft 33, journaled on the bridge 1 and carrying a sprocket34. A chain connects sprocket 34 with a sprocket 36 mounted on a shaft37 journaled in the frame and provided with a spur gear 38 meshing witha drive gear 39 carried by the remaining front wheel 2. A clutchmechanism 40 on the shaft 37 actuated by a shifting lever 41 pivoted,for instance, on the axle 3 controls the operation of the belt conveyer.

It will be noted that shaft 37 rotates in a direction opposite to thatin which shaft 26 rotates, and in order to control the operation of theconveyer and of the kickers through a single means, we provide a lever42 connected by a link 43 to one arm of a pivotally supported bell crank44, the opposite arm of which bell crank is secured to a connecting link45 extending between the free ends of the respective shifting levers 31and 41. Movement of the lever 42 in one direction or the other willthrow both clutches in or out, respectively.

In order to drop the hay in cocks we provide the following mechanism.Suspended beneath the elevated portion 1 of the frame is a hopper 17generally frusto-conical in shape, and comprising twosemi-frusto-conical members independent of each other, such membersbeing semi-circular at their upper ends and having downwardly inclinedor sloping bottoms 46 which coperate to close the lower end of thehopper when the members are in their vertical positions. Thesemi-circular upper ends of the members are secured in any suitablemanner to semi-annular bars 47 offset at their opposite ends as at 48,the offsets on one bar adapted to overlap the offsets of the oppositebar, the two semi-annular bars cotiperating to form a horizontallydisposed ring having offset portions at diametrically opposite points.Pivot pins 49 pass through these opposite overlapped offsets, wherebythe two members forming the hopper are arranged to swing outward awayfrom each other and laterally relative to the travel of the machine. Thepivot pins are supported in the cross braces 50, 50 of the elevated part1 of the frame. The offsets are formed to give clearance to thesemi-conical members as they swing toward and from each other andrelative to the cross braces 50. As one means for mechanically actuatingthe members of the hopper 17, we provide the hooks 51 loosely connectedby the straps 52 to the semi-conical members near their lower ends. Theshanks of the hooks are notched as at 53 (see Fig. 4) and pass looselythrough slots 54 formed in the respective projecting ears 55 secured tothe longitudinally extending bars of the elevated portion of the frame.The rear ends of said ears are apertured as at 56. Cables 57 passthrough the apertures and are secured at their lower ends to the hooks51. The opposite ends of the cables are wound on the drums 58 mountednear the opposite ends of a counter-shaft 59 journaled near the rear endof the elevated portion above the hopper 17, such shaft being providedwith a sprocket 60 connected by a chain 62 to a second sprocket 61 onthe upper roll shaft A clutch mechanism 63 011 the roll shaftcotiperates with the sprocket 61, the clutch being operated by a lever64 extending forwardly to the drivers seat 65 near which are alsolocated the levers 1S and 42.

The operation of the rakes, kickers and conveyer has been heretoforedescribed.

hen the conveyer has deposited a sufii cient amount of hay in thehopper, which is larger at the bottom than at the top, the driver willactuate lever (34 to throw in clutch 63 and thereby impart motion to thecounter-shaft 59 to wind the cables 57 thereon. The lower ends of thecables being secured to the offset ends of the hooks which hooks liesome distance laterally of the vertical plane of the pivot pins 49, willoperate to swing the hopper sections away from each other to dump theload in a cock or pile, the movement of the sections away from eachother being rapid and the sloping bottoms 46 facilitating the dischargeof the hopper contents. The notches in the shanks of the hooks 51 takeover the edges of the slots in the cars 55 and operate to lock thehopper sections in closed position. Therefore, before the sections canbe swung open, it is necessary to release the shanks from the cars. Thisis accomplished by the upward pull of the cables on the free lower endsof the hooks which operates to swing the hooks inwardly by reason oftheir loose connection through straps 52 with the hopper sections, andas the sections move upwardly, the shanks of the hooks slide in theslots 54. As soon as the hopper has discharged its load, the clutch G3is thrown out whereupon the hopper sections return to their closedpositions by gravity, unwinding the cables, and the notches in the hooksautomatically take over the edges of the slots 54 to lock the hoppersections in position again. It takes but a small space of time todischarge the contents of the hopper and return the sections to closedposition. The countershaft 59 is set back from the upper open end of thehopper so as not to impede the delivery of the hay t-hereinto.

From the foregoing, it is plain that we have devised an efficientmachine for raking the hay or other material and leaving it in cocks orpiles. WVe have also devised a hay cocker, the hopper of which is notrotated I which would place unnecessary strain on the machine andnecessitate a stoppage of the rake until the hopper is reversed anddumped. In some instances, indeed, it is necessary in former machinesfor the driver to get off his seat and go to the rear of the machine inorder to properly dump the hopper.

It is evident that changes might be made in the form and arrangement ofthe several parts described without departing from the spirit and scopeof our invention.
